UNC6384 Deploys PlugX via Captive Portal Hijacks and Valid Certificates Targeting Diplomats

UNC6384 Deploys PlugX via Captive Portal Hijacks and Valid Certificates Targeting Diplomats

Aug 25, 2025 Malware / Cyber Espionage
A China-nexus threat actor known as UNC6384 has been attributed to a set of attacks targeting diplomats in Southeast Asia and other entities across the globe to advance Beijing's strategic interests. "This multi-stage attack chain leverages advanced social engineering including valid code signing certificates, an adversary-in-the-middle (AitM) attack, and indirect execution techniques to evade detection," Google Threat Intelligence Group (GTIG) researcher Patrick Whitsell said . UNC6384 is assessed to share tactical and tooling overlaps with a known Chinese hacking group called Mustang Panda , which is also tracked as BASIN, Bronze President, Camaro Dragon, Earth Preta, HoneyMyte, RedDelta, Red Lich, Stately Taurus, TEMP.Hex, and Twill Typhoon. The campaign, detected by GTIG in March 2025, is characterized by use of a captive portal redirect to hijack web traffic and deliver a digitally signed downloader called STATICPLUGIN. The downloader then paves the way for the...
Docker Fixes CVE-2025-9074, Critical Container Escape Vulnerability With CVSS Score 9.3

Docker Fixes CVE-2025-9074, Critical Container Escape Vulnerability With CVSS Score 9.3

Aug 25, 2025 Container Security / Vulnerability
Docker has released fixes to address a critical security flaw affecting the Docker Desktop app for Windows and macOS that could potentially allow an attacker to break out of the confines of a container. The vulnerability, tracked as CVE-2025-9074 , carries a CVSS score of 9.3 out of 10.0. It has been addressed in version 4.44.3. "A malicious container running on Docker Desktop could access the Docker Engine and launch additional containers without requiring the Docker socket to be mounted," Docker said in an advisory released last week. "This could allow unauthorized access to user files on the host system. Enhanced Container Isolation (ECI) does not mitigate this vulnerability." According to security researcher Felix Boulet, the vulnerability has to do with how it's possible for a container to connect to the Docker Engine API at 192.168.65[.]7:2375 without requiring any authentication, thereby opening the door to a scenario where a privileged container c...
Phishing Campaign Uses UpCrypter in Fake Voicemail Emails to Deliver RAT Payloads

Phishing Campaign Uses UpCrypter in Fake Voicemail Emails to Deliver RAT Payloads

Aug 25, 2025 Malware / Cloud Security
Cybersecurity researchers have flagged a new phishing campaign that's using fake voicemails and purchase orders to deliver a malware loader called UpCrypter . The campaign leverages "carefully crafted emails to deliver malicious URLs linked to convincing phishing pages," Fortinet FortiGuard Labs researcher Cara Lin said . "These pages are designed to entice recipients into downloading JavaScript files that act as droppers for UpCrypter." Attacks propagating the malware have been primarily targeting manufacturing, technology, healthcare, construction, and retail/hospitality sectors across the world since the start of August 2025. The vast majority of the infections have been observed in Austria, Belarus, Canada, Egypt, India, and Pakistan, among others. UpCrypter functions as a conduit for various remote access tools (RATs), such as PureHVNC RAT , DCRat (aka DarkCrystal RAT), and Babylon RAT , each of which enable an attacker to take full control of compromi...

⚡ Weekly Recap: Password Manager Flaws, Apple 0-Day, Hidden AI Prompts, In-the-Wild Exploits & More

Aug 25, 2025 Cybersecurity News / Hacking
Cybersecurity today moves at the pace of global politics. A single breach can ripple across supply chains, turn a software flaw into leverage, or shift who holds the upper hand. For leaders, this means defense isn’t just a matter of firewalls and patches—it’s about strategy. The strongest organizations aren’t the ones with the most tools, but the ones that see how cyber risks connect to business, trust, and power. This week’s stories highlight how technical gaps become real-world pressure points—and why security decisions now matter far beyond IT. ⚡ Threat of the Week Popular Password Managers Affected by Clickjacking — Popular password manager plugins for web browsers have been found susceptible to clickjacking security vulnerabilities that could be exploited to steal account credentials, two-factor authentication (2FA) codes, and credit card details under certain conditions. The technique has been dubbed Document Object Model (DOM)-based extension clickjacking by independent sec...
Why SIEM Rules Fail and How to Fix Them: Insights from 160 Million Attack Simulations

Why SIEM Rules Fail and How to Fix Them: Insights from 160 Million Attack Simulations

Aug 25, 2025 Network Security / Threat Detection
Security Information and Event Management (SIEM) systems act as the primary tools for detecting suspicious activity in enterprise networks, helping organizations identify and respond to potential attacks in real time. However, the new Picus Blue Report 2025 , based on over 160 million real-world attack simulations , revealed that organizations are only detecting 1 out of 7 simulated attacks , showing a critical gap in threat detection and response. While many organizations believe they're doing everything they can to detect adversary actions, the reality is that a large number of threats are slipping through their defenses unnoticed, leaving their networks far too vulnerable to compromise. This gap in detection creates a false sense of security when attackers have already accessed your sensitive systems, escalated their privileges, or are actively exfiltrating your valuable data. Which begs the question: why, after all this time, money, and attention, are these systems still ...
Transparent Tribe Targets Indian Govt With Weaponized Desktop Shortcuts via Phishing

Transparent Tribe Targets Indian Govt With Weaponized Desktop Shortcuts via Phishing

Aug 25, 2025 Malware / Cyber Attack
The advanced persistent threat (APT) actor known as Transparent Tribe has been observed targeting both Windows and BOSS (Bharat Operating System Solutions) Linux systems with malicious Desktop shortcut files in attacks targeting Indian Government entities. "Initial access is achieved through spear-phishing emails," CYFIRMA said . "Linux BOSS environments are targeted via weaponized .desktop shortcut files that, once opened, download and execute malicious payloads." Transparent Tribe, also called APT36, is assessed to be of Pakistani origin, with the group – along with its sub-cluster SideCopy – having a storied history of breaking into Indian government institutions with a variety of remote access trojans (RATs). The latest dual-platform demonstrates the adversarial collective's continued sophistication, allowing it to broaden its targeting footprint and ensure access to compromised environments. The attack chains begin with phishing emails bearing sup...
